Specification of Letters Patent. I

Patented April 7, 1908.

Application filed October 15, 1907. Serial No. 397,588.

To all whom it may concern:

Be it known that I, CLARA A.- RIoKARDs, of Portland, county of Multnomah, and State of Oregon,- have invented a new an useful Improvement in Electric Curling Irons, of which the, following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention relates to improvements in contact devices used primarily in connection with electric curling irons. I v The )rime object of the invention is to provide a locking connection between a key and handle of the iron, to insure of the parts being securely held together, at the same time permitting of ready and convenient attaching and detaching of the iron.

The inventionalso com rehends improvements inthe specific details of construction, which will be hereinafter referred to and particularly pointed out in the claims.

In the drawing-Figure 1 is a side elevation of my improvement applied to an elecsocket.

trio curling iron. Fig. 2 is an enlarged detail erspective view of the key a plied to a hantle. is a detail side e evation of the key. Fig. 4 is a detail longitudinal section of the end of the handle-having a key Fig. 5 is a detail horizontal section on the line 55, Fig. 4.

The numeral 1, indicates an electric heating iron, comprisingtwo members 2 and 3, provided with hand s 4 and 5, but as the construction of this device is so well known, 1t is not thought necessary to refer to it in detail.

The handle 4, is formed in its end with an elongated key socket 6, having an enlargement 7, at its inner end, to form a shoulder 8.- The shoulder is notched at 9-9, about one plane with the center of the socket 6, in which the opposite ends of a cross bar of a key 10, are seated when the parts are connected. In the notches 9, are the terminals '1 1, of the heating coils which h eat the iron.

with current. The inner end 0 t e key has a} cross bar 15, extending from opposite sides of the stem. The ends of the cross bar facing the finger piece 14,.have two'contact points 17, to which the wires supplying the current are attached.

. In use, the cross bar 15, is forced into the socket 6, until the enlargement 7, is reached, and then the key given a quarter turn to bring theends of the bar opposite the notches 99. When in this position the key is given a slight rearward movement to bring the ends of the cross bar into the notches 99, toalock the key in the handle. To unlock the key, it is pushed inwardly, to disengage the cross bar min the notches, and then it is givena quarter turn to bring said bar into alinement with the socket 6, when the key can be withdrawn.

The invention is simple, and by the construction shown and described the contact is effective.

end, the inner end of said slot communicating v with two radial grooves havin short ri ht angle with t aving two handles, one of said' portions extendihg there om para lele slot, a wire terminal in the end of each extended portion of the radial grooves, 3

a key including a stem, and an angularly'disposed cross-bar on the end of the stem, the' 1c extensions are reached the ends of the bar into said ri ht angle portions to cause the terminals in t e handle and cross-bar to contact.

In testimony whereof I affix my signature in presence of two witnesses.
